Introduction: Premenstrual Syndrome is a complex of physical, mental and emotional symptoms headed by depression, anxiety and aggressive behaviors. Therefore, this study aimed to evaluate the effectiveness of anger management skills on the symptoms of premenstrual syndrome among the seventh grade girls.

Materials and Methods: In a single study tested a multiple baseline, the treatment processes were performed on four teen girls of seventh and eighth graders at before, during and after the intervention. The scale of intervention were mental distress (SUDs, 1966), depression Inventory second edition (BDI-II, 2008), Beck anxiety Inventory (BAI, 1992) and Barratt Impulsiveness scale (BIS, 1994). For objectifying of the rate of recovery; percent formula of improvement was applied. AO was the Questionnaire scores measured at baseline, A1 the same score in the last session and %DA is the rate of their change.

Results: Our results have shown that anger management skills training can improve subjective units of distress scale of life skills. About the variable of depression score, the first participant is lower than the rest and the overall improvement in the subjects was 43%. About anxiety scale, the greatest impact were seen in second, third and fourth subjects respectively. In first subject effectiveness of anger management was not statistically significant. But in impulsivity; all four subjects were showed significant effectiveness.

Conclusion: Although the current study lacked a control group, but the findings of this study indicated on the generalizability of these findings to risky behaviors. Finally, it seems that life skills training is an effective method, but to further evaluation of its effectiveness, more studies by control group are necessary.
